The reason there is a difference between the mass of the candle before and after burning is that <u>C. Some of the </u><u>candle wax </u><u>was </u><u>converted </u><u>into</u><u> light energy. </u>
When a candle is being burnt, the candle wax acts as a fuel for the fire. This wax is burnt by the fire such that heat and light energy are formed. The candle wax was therefore converted from chemical energy to light energy.
The other options are wrong because:
- Gases escaping won't reduce mass of candle
- Masses were not the same after the candle was burnt
- The law of conservation of mass still applies but the mass simply transferred to another form
In conclusion, the mass of the candle changed because some of the wax was converted to light energy.
